When 400 grams of wood are burned 30 grams of ash remain what happened to the other 370 grams of matter?

What causes wood and gas to give off heat when they're burned?

When wood or gas is burned, heat is produced due to the process of combustion. Combustion is a chemical reaction that takes place between the fuel (wood or gas) and oxygen in the presence of heat, resulting in the release of energy in the form of heat and light. The fuel undergoes oxidation, breaking down into simpler molecules and releasing heat energy in the process.
